摘要

我们介绍了一个框架，用于从位于随机分布的传感器阵列中间的源获取信号。这个问题出现在麦克风阵列的语音采集中。基于心理声学的考虑，我们提出了一个约束优化问题，其中阵列权重的选择最小化对远场源的响应，同时保持源信号的单位增益约束。

Beamforming for a source located in the interior of a sensor array

We introduce a framework for acquiring a signal from a source that is located within the midst of a randomly distributed sensor array. This problem arises in speech acquisition with microphone arrays. Based on psychoacoustic considerations, we formulate a constrained optimization problem in which the array weights are chosen to minimize the response to farfield sources while maintaining a unity-gain constraint for the source signal.
